<p>Reports methods with mutator-like names that have no parameter clauses.</p>

<p>For a method with <a href="https://en.wikipedia.org/wiki/Side_effect_(computer_science)">side effects</a>,
    it is convention to have an empty parameter clause to indicate that it is not just an accessor method.</p>

<p>The quick-fix adds an empty parameter clause.</p>
<p><b>Example:</b></p>
<pre><code>
  trait Test {
    def updateAll: Boolean
  }
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
  trait Test {
    def updateAll(): Boolean
  }
</code></pre>
